Regression: Empty TODO lines

[Carsten Dominik <carsten.dominik@gmail.com>]

Hi Nicolas,

commit dfcb6faef11a2439b56b18a6289803361d402130 (Provide more consistent regexps for headlines)
makes the global TODO list fail on headlines with a TODO keyword but no text following:

* TODO This one works
* TODO
  This one fails (note, there is not even a space after TODO.

While I agree that a TODO line with not text is not good, I think
it should not break the TODO list view.  I am attaching the backtrace.

Cheers

- Carsten
